276 PERIZOMA. By L. B. Prout. 
band attenuated behind and somewhat interrupted, the wings perhaps relatively more elongate. Formosa, 
without indication of exact locality. 
P. triplagiata Warr. (= biplagiata Wileman, err. transcr.) (27 g). Forewing almost unmarked excepting 
the three dark patches from which it derives its name. Warren indicates that it may conceivably be a very 
different form of tenu fascia, but, apart from the other differences, it has an ochreous suffusion which is wanting 
in that species. Khasis (loc. typ.) and Simla. 
P. fractifasciaria Leech (Vol. 4, pi. 7 i). Whiter than costinotaria, the midcostal dark patch broader, a 
small mark opposite to it on the hindmargin (as in costata ab. particulata) . Ta-tsien-lu, 1 <$. Also 1 from Yunnan. 
P. brevifasciata Warr. (Suppl.-Vol. 4, pi. 16 b). Position somewhat doubtful. Antenna of the <$ shortly 
ciliate, 1st radial of the forewing not stalked, hindwing not quite regularly rounded. The type of maculation 
is somewhat as in fractifasciaria but much more copious, a band developed between the basal and the median, 
a line intersecting each white band, dark outer shades stronger. Thundiani (type) and Darjiling. 
P. cerva Hmps. (27 g). Much smaller than triplagiata, the glossy white forewing much suffused with 
cinnamon-buff, the midcostal mark greatly reduced, the subterminal costal somewhat extended, very near the 
apex. Sikkim, 7000 feet (type) and Upper Burma. Palpus rather long. 
P. lacernigera Butl. (Suppl.-Vol. 4, pi. 14 k). This and the following have also elongate palpi and are 
probably related to cerva but are less brightly coloured and more normally marked, the last costal spot not 
so near the apex, lacernigera is generally smaller than hockingii and has the termen of the forewing somewhat 
more sinuous. Further differentiations are given under hockingii. Both were described from Dharmsala and 
extend through Sikkim to N. Burma. 
P. hockingii Butl. (Vol. 4, pi. 7 k). Less glossy. Basal patch of forewing generally more oblique, central 
band better developed, less narrow, generally formed of a pair of dark lines connected by a costal blotch: fringe 
scarcely so sharply marked. Specimens from the Nagas, so far as they are known to me, are larger. 
P. rectifasciata Hmps. Lines and bands more equally expressed throughout the forewing than in the 
two preceding, approximately parallel and without any very strong projections; tone of colour somewhat as 
in decorata. Hindwing somewhat less weakly marked than in most Perizoma. Sikkim, 7000 feet, apparently 
very rare. 
P. decorata Moore (27 g). A neat little species, with sinuous median band (weakly indicated also on 
the whiter hindwing) and fairly conspicuous anterior half-band proximal to the subterminal, the subterminal 
more or less macular and with a large spot or longitudinal streak in the middle. Sikkim. quadrinotata Warr. 
from Assam and Upper Burma (the type from the Khasis) is possibly a separable race as the majority of the 
specimens — especially from the Khasis — are more strongly marked; but there is considerable variation 
and Hampson was perhaps right in treating the two forms as synonymous. 
P. simulata Wileman. Similar to decorata , indeed Wileman considers that some of the Sikkim specimens 
determined as decorata in the British Museum agree with his species. His unique type, however, a from 
Arizan, Formosa (7300 feet), is much less brightly coloured — whitish with the markings grey-brown, the sub- 
terminal spots not quite characteristically developed. It should be, I think, at least a subspecies. 
P. puerilis Prout (Suppl.-Vol. 4, pi. 16 a). Antennal filiation of the £ minute. Paler than decorata, fore¬ 
wing with apex more acute, termen more sinuous, median band narrow throughout, scarcely sinuous, sub- 
terminal spots formed much as in decorata, their dark proximal shade developed chiefly in cellule 5, i. e. just 
in front of the longitudinal white streak. Htawgaw, Kachin Hills, the type <$; besides, I know only a labelled 
“W. China”. Superficially recalls the S. American genus Psaliodes. 
P. ochreotincta Wileman (27 g). Wileman considers this also allied to P. “decorata" ; perhaps this is 
so, but the type — unfortunately rubbed — looks to me to have more affinity with fasciata or others of the 
taeniata group; it is hoped that our figure will give a correct impression of it. Basal and median bands well 
defined, blackish, the latter bilobed distally, costal subterminal patch bearing 3 white dots. Rantaizan (type) 
and Arizan, Formosa. 
P. parvaria Leech (= ablegata Stgr.) (Vol. 4, pi. 7 k)., Recognizable by its rather characteristically 
shaped median band, which has its distal boundary and the lines which are parallel therewith not dentate, but 
merely once sharply bent; distal area partly white opposite the angle. The originals were “probably from 
Yokohama", later material from Yamato, the Ussuri and W. China. Palpus rather short. albidivisa Warr. 
(27 g), described from the Naga Hills and known in similar forms from the Khasis and N. W. India, is perhaps
